PREPARATION BEFORE ADJUSTING
NOTE:
 For details, refer to the regulations in your own country.
 Perform aiming if the vehicle front body has been repaired and/or the headlamp assembly has been
replaced.
Before performing aiming adjustment, check the following.  Adjust the tire pressure to the specification.
 Fill with fuel, engine coolant and each oil.
 Maintain the unloaded vehicle condition. (Remove luggage from the passenger compartment and the trunk
room.)
NOTE:
Do not remove the temporary tire, jack and on-vehicle tool.
 Wipe out dirt on the headlamp.

Aiming Adjustment Procedure (Low Beam)
INFOID:0000000003774533
1. Place the screen.
NOTE:
 Stop the vehicle at the perpendicular angle to the wall.
 Set the screen so that it is perpendicular to a level load surface.
2. Face the vehicle squarely toward the screen and make the distance between the headlamp center and
the screen 10 m (32.8 ft).
3. Start the engine and illuminate the headlamp (LO).
NOTE:
Block light from the headlamp that is not being adjusted with a thick fabric or another object, so that it
does not reach the adjustment screen.
CAUTION:
Do not cover lens surface with tape, etc. because it is made from plastic.
4. Use the aiming adjustment screw to adjust the elbow point projected by the low beams on the screen, so
that it is within the aiming adjustment area.

DescriptionINFOID:0000000003773617
PREPARATION BEFORE ADJUSTING
NOTE:
 For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
 Adjust the tire pressure to the specification.
 Fill with fuel, engine coolant and each oil.
 Maintain the unloaded vehicle condition. (Remove luggage from the passenger compartment and the lug-
gage room.)
NOTE:
Do not remove the temporary tire, jack and on-vehicle tool.
 Wipe out dirt on the headlamp.
CAUTION:
Never use organic solvent (thinner, gasoline etc.)
 Ride alone on the driver seat.
AIMING ADJUSTMENT SCREW
 Turn the aiming adjusting screw for adjustment.
 For the position and direction of the adjusting screw, refer to the
figure.
NOTE:
A screwdriver or hexagonal wrench [6 mm (0.24 in)] can be used
for adjustment.
Aiming Adjustment ProcedureINFOID:0000000003773618
1. Place the screen.
NOTE:
 Stop the vehicle facing the wall.
 Place the board on a plain road vertically.
2. Face the vehicle with the screen. Maintain 10 m (32.8 ft) between the front fog lamp center and the
screen.
3. Start the engine. Illuminate the front fog lamp.
CAUTION:
Never cover the lens surface with a tape etc. The lens is made of resin.
NOTE:
Shut off the headlamp light with the board to prevent from illuminating the adjustment screen.
4. Adjust the cutoff line height (A) with the aiming adjustment screw so that the distance (X) between the hor-
izontal center line of front fog lamp (H) and (A) becomes 200 mm (7.87 in).
